In a medium pot, saute the onion in the olive oil for 2 minutes. Add the celery, green onion, red pepper, and zucchini, and saute an additional 5 minutes to soften the vegetables. Add the acorn squash, red skin potatoes, garlic, ginger, salt, basil, oregano, thyme, ground pasilla, and black pepper, stir well to combine, and saute the mixture an additional 3 minutes. Add the water, corn, and parsley, and bring the mixture to a boil. Cover, reduce the heat to low, and simmer for 30 minutes or until the vegetables are soft. In a small bowl, place the cornstarch, pour the cold water over the top, and stir until smooth. Add the cornstarch mixture to the simmering soup, stir well, and continue to cook the soup over low heat until thickened. Add the red beans and stir well to combine. Taste and adjust seasonings, as needed.
